# NNTP Protocol Details

Microsoft Exchange Server enables clients to participate in online discussions over an intranet or the Internet using Network News Transfer Protocol (NNTP) newsgroups. NNTP can be enabled on a per-mailbox basis.

1. On the Exchange Advanced tab, click Protocol Settings. The Protocols dialog box is displayed.
2. Click NNTP, and then click Settings.
3. To enable the protocol for this mailbox, select the Enable for mailbox check box. To disable the protocol for this mailbox, click to clear the Enable for mailbox check box.
4. To use NNTP protocol defaults for Multipurpose Internet Mail Extensions (MIME) encoding, default character set, rich-text format, public folders, fast message retrieval, and user delegation, select the Use protocol defaults check box. When selected, all remaining options in the NNTP Protocol Details dialog box are unavailable. To use settings other than the default, click to clear the Use protocol defaults check box.

5. MIME defines a rich set of content types consisting of mail headers and body parts. These types allow for more definition of the message content such as media type. UNIX-to-Unix Encode (UUENCODE) defines an e-mail standard that compresses messages containing 8-bit data into messages containing 7-bit data for transmission in older e-mail environments. Additional encoding provides support for Macintosh BinHex file format. Select either MIME or UUEncode for a Message encoding option.
